1. In a group of people solicited by a charity, 30% contributed Tk 40, 45% contributed Tk 20 and the rest contributed Tk 2. If the charity received a total of Tk 300 from the people who contributed Tk 2, how much was contributed by the entire group?
- A. Tk 12600
- B. Tk 12600
- C. Tk 12600
- D. Tk 12600
Answer: Option D
Explanation:
Here, the rest is=(100-45+30)%=25%
People who contributed with 2 taka=(300/2)=150
Now,
25% means 150
So, 30% means (150×30)/25=180 people
So, 45% means (150×45)/25=270 people
Total contributed
=300+(180×40)+(270×20)
=12900 taka
